Answer:

Total Memory= 4 KB = 4096 bytes = 32768 bits

Explanation:

1. Data lines are 8 From D0 to D7

Total memory at single address locations is 8 bits.

2. Address lines are 12 (A0 to A11)

There are 12 address lines but 3 out 12 are for selction of chip or memory bank.

so only 9 pins are there to address the locations on one chip.

Total No. of address locations on single chip = 2^9 = 512 locations

as 1 location is 1 byte so total memory of single chip is 512 bytes.

3. Total Memory Bank 

There are total 3 selection pins for memory bank.

Total chips = 2^3 = 8.

4. Total Memory 

Total size of 1 chip = 512 bytes

Total size of 8 chip = 8x512 bytes = 4096 bytes = 4096/1024 kb = 4 kb

So total memory of system is 4 Kb = 4096 bytes = 32768 bits

Explain three reasons why so many different computer languages exist. Pleaseeee

zmey [24]

Each language has its own use, some of them are used to create or manipulate back end codes and some of them are used mainly for web designing and some of them are used for data entries and control of data that is being implanted in the system, so if you put all uses in one language it will not be a simple task as it is nowadays for programmers. That is why there are different compt. langs.
